Season both sides of the chuck roast with salt and pepper.
In a large skillet over medium-high heat, add butter and melt. Sear each side of the roast for 3-4 minutes. Then, add to the slow cooker.

Remove roast and thinly slice against the grain. Add roast back into juices in the slow cooker.

Notes
Sear the beef for a few minutes on each side to lock in the flavor and juices of the meat before adding it to the slow cooker.
Chuck roast is a tough cut of beef, so cook it low and slow in the crock pot to make it tender and juicy.
Slice your beef against the grain, which means cut the meat perpendicularly across the muscle fibers to shorten them. This makes the meat less chewy and better for a sandwich.
